At around 9 p.m., while Li Xiangping was waiting for the "master" to make his next move, in a corner of Europe, Google's AlphaGo team was also waiting for the dog to make a move.

Today, Fan Erduan and Yan Qing are both present.

Since being defeated by Afagou 5-0 in the first test, Fan Erduan has basically become a formal member of the development team. At first he accepted the invitation, and now he takes the initiative to join in. As this type of scientific research team, it also needs

There are professional chess players who serve as consultants, so Dr. Huang and the others certainly welcome Fan Erduan and Yan Qing's initiative to join them.

"Hey, it's been 8 minutes! The machine hasn't made any moves for 8 minutes. This has never happened before. Dr. Huang, please take a look and see if there is any other malfunction..."

However, after inspection by relevant team personnel, the machine was operating normally and no other faults were found.

"Call up the background data and see the real-time winning rate displayed by the machine..."

After this review, the reason for the "long test" of the machine seems to have been found.

Thirty-nine point eight percent!

When Li Xiangping landed on White 66, the background data showed that Black's winning rate instantly dropped to 39.8%.

Everyone was shocked.

Besides being surprised, many people were also a little excited.

Because now everyone knows that if the Japanese and Korean rules are followed and black is posted with 6 and a half mesh, the dog will think that black will suffer a slight loss.

So when Black makes his first move, Black's starting winning rate is about 47% to 48%.

If Chinese rules were followed, Black's initial winning rate would be even lower, only about 43 to 44 percent.

However, in the previous 60 test games, even if the "master" played black, as long as 50 moves passed, the winning rate displayed in the background was never lower than 50%, and most of them were already above 60%.

.

However, today, the real-time winning rate of "master" has actually dropped below 40%. This is the first time this has happened.

When Fan Erduan saw this, he sighed:

"Tsk, tsk, Li Xiangping is still awesome. He is worthy of being a Go genius who only comes out in 500 years. Hehe, the important task of safeguarding human dignity can only fall on his shoulders now. By the way, Yan Qing, you were the one back then.

Known as Li Xiangping’s nemesis, why don’t you continue?”

"It's important for people to know themselves."

Yan Qing responded with a smile, a little proud in his voice:

"If I continue to play professional Go, I will know my own weight. You see how good I am now. Because I no longer play chess, some people still remember that I was Li Xiangping's nemesis. But if I had persisted at that time, I might not even be in the first round now."

I can’t even hit it, hey, it moved, the machine seems to have prompted the move..."

After nearly 10 minutes of "long exam", the "master" finally announced the move, so everyone's chat ended and they continued to pay attention to this special man-machine battle.

Back in the capital, Li Xiangping has certainly not been idle in the past 10 minutes. Of course, he also has to predict where his opponent may make a move.

The moment he saw Black 67, Li Xiangping's nerves relaxed inexplicably----

Not because of anything else, because the dog's move was within his expectations.

He had just considered three or four options, and the dog's choice was actually the first option in Li Xiangping's mind.

When competing with dogs, Li Xiangping thinks this is very important. As long as you can guess the dog's next move, no matter how sophisticated the move is, there is always a way to deal with it. The worst thing is that you think like this,

Then the dog suddenly lands in a place you didn't expect at all, and that would be very bad.

The reason why Li Xiangping was able to predict the "master"'s black 67 was because the dog's chess move still conformed to the general human chess theory.

In fact, when Li Xiangping learned dog moves in the past, he always used human thinking to summarize dog moves using the chess principles summarized by humans.

Now that the dog's chess move is in line with "human chess principles", Li Xiangping's nerves naturally relax.

So what human chess theory does the "master's" move conform to?

There is a saying in human Go, which is "If you can't respond well, don't respond."

As for Li Xiangping's previous White 66, in addition to completely reinforcing itself and leaving no flaws in White's chess shape, this move also had another effect, that is, it completely turned the center of the chessboard into a "salt-alkali land", leaving no trace of any flaws.

Any black piece is a "good point".

Yes, sometimes Go is so wonderful. For example, today's game, although it is just a typical offensive and defensive game, the biggest focus is the appearance of black in the center.

But after Li Xiangping's White 66, it seems that Black is no longer suitable to continue playing chess in the middle generation.

No matter where it is placed, there will always be suspicion of forcible encirclement.

And "Thick power does not surround empty space", this is also the chess principle summarized by human beings.

This is because of the "golden-horned silver-edged grass belly". If you want to forcefully surround the mid-belly generation, your effectiveness will often become low.

Obviously, the principle of "golden horns and silver-edged grass belly" also applies to dog Go. No matter how powerful the dog is, it cannot maintain high efficiency when it is forced to encircle the midsection.

This is another main reason why Li Xiangping is satisfied with his Bai 66 -------

In this chess move, the white spots in the middle area are all salt-alkali land, and there is no good point in sight. In order to maintain the effectiveness of his pieces, Black is forced to put aside the problem of the middle area for the time being and find ways to open up new areas elsewhere on the chessboard.

battlefield.

As for the dog's black 67, it is true that he did not continue to play chess in the middle generation, but moved to the upper right corner of the chessboard.

The dog's hand is black 67. From the perspective of an official, this hand is worth about eighteen and a half eyes to a high official.

There are currently less than 70 moves, and it may seem a bit strange to enter the official stage at this time, but after carefully analyzing the situation of this game, it is actually not surprising at all.

Not to mention that the eighteen-and-a-half-movement itself is of great value, but more importantly, the shape of the white chess piece is extremely solid, and there is currently no place that can be impacted.

Since there is no "urgency" anymore, the game ends after more than 60 moves. This is also very common in human Go.

And forcing the dog to accompany him from more than 60 hands to the end, this is the second place where Li Xiangping is satisfied -------

The advantage of dogs lies in the overall situation and "realm". In Li Xiangping's understanding, the so-called "overall situation" and "realm" are those big chess pieces worth twenty or thirty moves.

At Li Xiangping's current level, any chess piece worth less than 20 moves can be called an official piece, and this is something he can control.

If the dog is dragged into an area that he can control to compete, then from Li Xiangping's perspective, he will certainly be satisfied.

Of course, the situation on the chessboard changes rapidly. Sometimes there is a big fight for an eye and a half, and then there are unexpected battles or transitions. This is not uncommon in human Go.

Therefore, although he got his wish, Li Xiangping relied on Bai 66 to temporarily achieve his strategic goal. At this time, he still did not dare to be careless. After seeing Black 67, Li Xiangping concentrated again, changed his mind at the same time, and prepared to start a fight with the dog.

A long-distance battle for officials.

Time passed bit by bit. When the time came to 9:30 in the evening and the game reached around 110, Li Xiangping accurately judged the situation and then asked his cheat:

"Brother Ding'an, what is your judgment?"

"Hey, I thought the white chess piece was slightly better, and the black chess piece was at most 5 to 6 points ahead on the board. What about the little friend from Xiangping?"

Li Xiangping smiled after hearing this. Just when he was about to say, "Heroes think alike," he suddenly couldn't say it.

Because at this moment, he saw the chess move the dog had just played.

This is move 113 of the overall situation.

This move was completely beyond Li Xiangping's expectations.

This is the only move that went beyond Li Xiangping's expectations starting from Black 67.

Li Xiangping took a deep breath at that time.

“The dog’s winning hand!”
